Abstract
Isobutylbenzene was synthesized by side chain alkylation reaction of toluene and propylene with the catalysis of sodium-potassium alloy.The effects of reaction temperature,reaction pressure,reaction time of propylene with toluene and the molar ratio of reactants on the yield of isobutylbenzene had been investigated.The results showed that the yield of isobutylbenzene reached 63.85% under the optimum conditions as follows:reaction temperature was 200 ℃,reaction pressure was 3.0 MPa,reaction time of toluene with catalyst was 1.5 h,reaction time of propylene with toluene was 3 h and molar ratio of propylene to toluene was 0.85∶1.
